As did those Jurassic Sauropod giants that emerged from the Wyoming badlands of a sorts.
Now part of at the Dinosphere show at: The Children's Museum of Indianapolis.
At least its a bone we can all chew on
I have some metal Connies [1085] paired with Conshelf XII, XIV, 14, SE first stages that should be good for not only the balance of my life, but that of my kids as well. Even without servicing these beasts could survive Armageddon.
Just Sayin'
Not much, he’s naming parts as they go in (extra body (what SP calls a dry chamber, idk what to call it
), coupled pistons 1&2, spring+adjuster, diaphragm+cover)What’s new to me is that that system eliminates the inner diaphragm and moves it up, unlike the mk17 or the ds4 (which have both a main diaphragm and the environmental seal), „the outer diaphragm will do both functions (control IP and seal)“
then some marketing on how that would be better than a double diaphragm system with more stable IP
(I did my best, not a native speaker)
I have the TBP on my 82X (a heavy reg) and on my 28XR. It's really quite ingenious (though not completely new - the Dacor Extreme had a plastic oring sealed sleeve piston that acted the same way).
In any case, this floating piston head acts like the diaphragm, sealing against a smooth inner sealing surface just like a piston reg. The pin that opens the valve is connected to the piston head, and the seal above is a similar floating piston-head-like device that accepts the load of the environmental seal. Connecting the two together maintains the alignment of the sealing piston head that substitutes for the diaphragm.
Thus you have a dry-sealed reg with all the advantages of a diaphragm (crisper lockup for longer) but no constantly flexing diaphragm.
Time will tell if the oring seal does better than the diaphragm, but at least no more of these:
Mares has tested the 28XR to 200m.

Maybe Mares' purchase of the corpse of Dacor finally paid off with something other than headaches and bad feelings.
I'm picturing an engineering intern being told to go through a bunch of boxes that were dumped off in 1998 (before he was born), seeing the testing docs on the Dacor Extreme and thinking, "You know. With a little work we might just have something here."
As a fan of both Dacor and Mares, I've owned several regulators from each company, it was indeed a sad day when Mares effectively killed off Dacor in order to acquire its distributors. Many excellent products immediately became obsolete due to parts kit discontinuation and lack of factory support. Lets hope this isn't the future for Aqualung.
After having a long discussion with the Mares Chief Engineer at DEMA, and several followup emails, I'm convinced that they're trying very hard to stay at the forefront. It's difficult to come up with new stuff for a 60-year-old basic valve design. But they're trying.
Not too many folks pass Norsok standards at 900+ feet!
Their new HP seat material pretty much leaves everything else in the dust.

Argh. Why do people keep repeating this? Mares didn't kill off Dacor. It was already dead. Dacor had ceased production of the few items it actually made, stiffed its suppliers who made most of the stuff sold under the Dacor name and was preparing for bankruptcy liquidation proceedings when Head offered to buy out whatever was left and fold it into Mares.
Yes, what they were primarily interested in was the dealer network. There were no true Dacor products still being manufactured to supply that network, but there was a full line of Mares' gear they could offer instead. For those dealers that still wanted to sell Dacor branded products, Head simply slapped the Dacor name on existing Mares products. This wasn't very effective and Mares eventually shut down the Dacor branded gear line entirely.
Mares did get whatever spare parts were left in the Dacor warehouse and they continued to distribute them until they were gone.
An obligation to produce new spare parts to honor Dacor's Lifetime Guaranty program was not part of the sale. Dacor could have tried to insist on it as part of the sale, but it likely would have killed the deal entirely as uneconomical. Mares did try to partially compensate Dacor reg owners for the loss of their warranty by offering to replace Dacor regs with heavily discounted Mares regs for a few years after the acquisition.
Something to keep in mind if you are planning your own scuba (as opposed to surface supplied) dive to 320m based on an internet post is that the standard (section 6.3.10) includes heating of the gases when exceeding 150m deep. For depths from 300m to 400m, the standard states that the incoming gas should be kept at 25±2°C.
